It's not quite the only book about Enterprise Architect. I've seen one although it was in Japanese. There are also a number of books primarily about Process, that specifically use EA features and use EA for examples throughout.

Still, looking at your table of contents, it looks like there are some worthwhile tips there and I hope it continues to sell for you.

That's one of the main reasons I turned to Leanpub: updates are for free and they will be announced automatically to readers.

The other main reason is cost. Printing & shipping costs a lot of money. With digital media, that is no longer the case. This means I can offer the ebook for one third of the price of the printed book.

"Just reading this now (Kindle version).Iíve been an EA user for 7+ years, and Iím now keeping a tally of the tricks I didnít know: and there are lots!This is a great piece of work, and has been needed for a long time.Iím just writing a ĎIntro to EAí course for a customer, and Iíll certainly reference it.Well done!"

I got no less than five mails with additional tricks and info, all from readers who have bought the e-version. I'll ask permission to include them in a new version, which will be offered as a free update.

Just added trick nį 55: how to add a bunch of relations with only a few mouseclicks... all current readers have been informed of the update and can download a new version for free at http://leanpub.com/entarch
